CatchAll vs Google Custom Search API: overview

CatchAll

CatchAll is the web search API from NewsCatcher (Y Combinator–backed), built around complete dataset retrieval rather than top-ranked results. CatchAll scans 50,000+ pages per job at ~10,000 pages/minute, applies LLM-based validation via Leiden algorithm clustering, and returns structured JSON records with source citations. In an independent March 2026 benchmark across 6,025 observable events, CatchAll achieved 79.8% recall and F1 score of 0.705 — compared to 0.317 for the next closest competitor. NewsCatcher is ISO-certified, SOC2 Type II–certified, and GDPR-ready, with 99.95% platform uptime and a 5-minute source-to-signal latency. Notable enterprise clients include the US Department of State, Samsung, UC Berkeley, HCOB, and Transparency International (per company website; independently unverifiable).

Google Custom Search API

Google Custom Search JSON API provides programmatic access to Google's Programmable Search Engine (PSE), formerly Google Custom Search Engine. Unlike a general web search API, the PSE only searches websites explicitly configured in the PSE console — it does not provide access to Google's full web index. Free usage is capped at 100 queries per day; beyond that, pricing is $5 per 1,000 queries with a hard 10,000 queries per day maximum per project. The API is part of Google Cloud and inherits its compliance framework including SOC 2, ISO 27001, FedRAMP, and GDPR. It has been available since approximately 2011.

CatchAll vs Google Custom Search API: pros and cons

CatchAll
+ Highest recall in independent benchmarks: 79.8% vs competitors' 26–32% across 6,025 observable events (March 2026)
+ Pay-per-validated-result pricing eliminates token waste — you only pay for records that pass LLM quality checks
+ Scans 50,000+ pages per job covering regional press, trade publications, and non-English sources most SERP APIs miss
+ Real-time event index with <5-minute source-to-signal latency and 2M+ events indexed daily
+ Enterprise-grade compliance: ISO-certified, SOC2 Type II, GDPR-ready, with 99.95% uptime SLA
+ Automated Monitors allow scheduled re-runs with built-in deduplication — no custom polling infrastructure needed
- Base mode jobs take ~15 minutes to complete — not suited for sub-second real-time query patterns
- Lite mode is capped at 100 results and lacks the full coverage depth of Base mode
- Smaller ecosystem and community compared to established providers like SerpAPI or Bing Search API
Google Custom Search API
+ Official Google product — the only legally compliant way to access Google search results via API without scraping risk
+ Full Google Cloud compliance: SOC 2, ISO 27001, GDPR, and FedRAMP through Google Cloud — covers regulated procurement
+ 100 free queries/day sufficient for internal tools, development environments, and low-volume dashboards
+ All Google API client libraries available (Python, Java, Node.js, Go, Ruby) — no custom HTTP client required
- Does NOT search the full Google web index — only searches sites configured in the Programmable Search Engine console
- 10,000 query/day hard cap per project makes it unsuitable for any production-scale search application
- $5/1K queries is 1.7–5× more expensive than Bing Search API for a more restricted index
- PSE configuration requires maintaining an explicit list of target sites — significant operational overhead for broad web search
